Soil bio-cementation treatment strategies: state-of-the-art review
نویسندگان
چکیده
Bio-cementation is a new sustainable approach that has gained popularity due to its low energy and carbon dioxide footprint compared with those of existing technologies for geotechnical geoenvironmental engineering applications. soil improvement technique involves binding the pore space particles calcium carbonate minerals by microbially induced precipitation (MICP) filling space. The purpose this paper present current state art comprehensive discussion on development bio-cementation improvement/reinforcement. Premixing, injection, immersing surface percolation are identified as four distinct treatment techniques. Furthermore, scholars have reported employing ureolytic bacteria such Sporosarcina pasteurii, Bacillus sphaericus Lysinibacillus isolated from corals, limestone caves, soils, waste materials, seawater other sources accomplish effective bio-cementation. Some major issues (bacterial cultivation costs ammonium production) impede industrial potential promising remedial techniques also discussed. This state-of-the-art review discusses benefits drawbacks traditional approaches. significance enzyme-induced alternative MICP highlighted. Finally, procedure, principles future implications

Bio-nanotechnology and photodynamic therapy--state of the art review.
Photodynamic therapy (PDT) and bio-nanotechnology (NT) show striking similarities in clinical design and mechanistics. The PDT paradigm of photosensitizer application, light activation and singlet oxygen generation does in fact occur on the nanoscale level as does the resultant outcomes. NT has the ability to explain as well as modify each of the critical steps of PDT particularly photosensitiz...
متن کاملTooth surface treatment strategies for adhesive cementation
PURPOSE The aim of this study was to evaluate the effect of tooth surface pre-treatment steps on shear bond strength, which is essential for understanding the adhesive cementation process. MATERIALS AND METHODS Shear bond strengths of different cements with various tooth surface treatments (none, etching, priming, or etching and priming) on enamel and dentin of human teeth were measured using...
